I also have a Rem 700 MR, but restocked into a B&C Ti stock & bedded well; shoots 51gr of RL-15 & 120 TSX into 5/8-3/4".
I seat all Barnes bullets to a very light kiss to .010" off.
But it shoots pretty much everything into 3/4" or better, all loaded to the same throat clearance.
In spite of what some on here claim about the need for seating Barnes bullets with a sizable jump to the lands, in the half dozen or so rifles I developed loads with them for, all have shot just fine kissing to .010" off the lands.
YMMV
